Study on TEA CO2 laser rapidly tuning system under the control of monolithic microprocessor

A new apparatus for TEA CO2 laser grate rapidly tuning system under the control of monolithic microprocessor is proposed.Some important techniques will be introduced in this proper,such as the design of triggering and tuning system,the principle of zero infra-red photoelectricity transducer,the control of stepping motor,the control software design and experimental research.This is a simple and usable open loop control system.
